Where we start
An overheated room is more than a BTU number. Windows, sunlight, noise and running costs matter too. Freath brings those questions together in guides and tools in French, German and English.
Swiss focus, clear boundaries
The project is designed around the Swiss context. That is not a Swiss Made certification or a claim of Swiss manufacture. Manufacturing origin and commercial information will be specified with the final product.
Clear about what is known
FREATH ONE is in development. We distinguish targets, calculation examples and validated measurements. We do not invent test results or customer feedback to promote the project.
